The Mouton Collared "Storm Coat"

The "Storm Coat" took the basic form of the trench coat, usually made in gabardine, and combined it with the construction of the sheeplined mackinaw, adding a mouton collar and either a sheepskin or an alpaca lining for extra warmth. Generally these coats had extremely padded, squared off shoulders, contrasted with the heavy drape of the material.  The coat on the far right illustrates this exaggerated shoulder the best. These were popular in the mid 1940s-early 1950s.
